Shortly thereafter he sent the lyrics to his old friend Major Zed who was so impressed by them he immediately wanted to do a complete rewrite. Doctroid collaborated in this, and then Major Zed made a recording.

Most of the vocals are synthesized, though Doctroid's and Major Zed's voices, heavily processed, are used in the intro/outro and bridge, respectively.

(8.) Left coset, right coset, normal subgroup, commutator - left cosets are aG, right cosets are Ga, a subroup G is normal if aG=Ga, a commutator is an element of the form (a)(b)(a^-1)(b^-1). This is all jargon from mathematical group theory (abstract algebra) which is important in quantum physics, God only knows why.

(10.) Knot invariants - quantities defined on knots that are the same for equivalent forms of the knot. For example, crossing number is the minimum number of crossings in a diagram of the knot. Boy scouts could be physicists.

(11.) Cauchy sequence - a mapping from counting numbers to a metric space where for any epsilon>0 there is an N such that... oh, never mind.

(12.) Butterfly catastrophe - one of the basic surfaces in Rene Thom's classification theorem (catastrophe theory). Not related to the "butterfly effect" (a butterfly flaps its wings and causes a hurricane). Not really, anyway.

(13.) Grassman bundle surgery - the Grassman manifold is the set of linear subspaces of a vector space. A bundle is locally a product of a vector space and a manifold. Surgery is the topological operation of defining the global structure of connectivity of a bundle. Think Moebius strip. Glad you asked?

(15.) Neutrino - chargeless, massless subatomic particle traveling at the speed of light. No, wait, it has a little bit of mass and it goes almost at the speed of light. But it has no charge. They think. Better check back next month.
